An average rainfall of 37.7 mm on Wednesday and 75.7 mm on Thursday recorded
VISAKHAPATNAM: Rain under the influence of Cyclone ‘Laila' has resulted in marginal improvement in the water levels of reservoirs that cater to the city with inflows into them. More importantly, it improved the groundwater levels.
Facing a severe water crunch, the city is mainly depending upon pumping of water from the lift irrigation scheme on the Godavari at Kateru near Rajahmundry and from the Yeleru canal. Though about 135 million gallons a day is being pumped, the actual realisation when it comes to the city is about 55 mgd.
Of that the domestic supply is 20 mgd. Tatipudi and Raiwada reservoirs are contributing 6.5 mgd and 12 mgd respectively.
The district recorded an average rainfall of 37.7 mm on Wednesday and 75.7 mm on Thursday.
Officials were not very enthusiastic about the levels till Thursday.
On Friday, the Raiwada reservoir with a level of 101.7 m recorded an increase of 55 cm, while Yeleru rose by 6 cm. Tatipudi reservoir improved by 1.5 ft, Meghadgrigedda reservoir by more than one foot, Mudasarlova by 4 ft and Gambhiram by 8 ft. The level at Kateru is being controlled owing to more inflows into the Godavari.
“Going by initial assessment the levels improved marginally,” said Superintendent Engineer (Water Supply) V. Chandraiah. With the catchment area of the reservoirs varying between 50 sq km and 2,000 sq km (Yeleru), it will take another two days to get a total picture, he added.
Prior to the rain under the influence of the cyclone, Gambhiram was totally dry and Mudarsarlova's contribution insignificant.
The Meghadrigedda Reservoir is serving as a storage reservoir for Godavari water. An infiltration well its downstream yields 1 mgd and from the Kanithi Balancing Reservoir 1.8 mgd is being drawn adding to the total supply.
